Squad Six was a squad composed of B1-series battle droids and under the command of an OOM command battle droid. This squad served within General Kalani's garrison stationed on the planet Agamar. Following a skirmish with a number of rebels belonging to Phoenix Cell, Squad Six suffered losses, with half of its members being destroyed, while the other half managed to survive. Subsequently, the Separatist holdout and the rebels put an end to their conflict and joined forces to combat the Galactic Empire. By the conclusion of the mission, Captain Rex, a former clone trooper, and Kalani came to terms, unofficially bringing the Clone Wars to a close; the surviving members of Squad Six then fled Agamar alongside Kalani and the rebels.
